Taking pictures of animals in their natural environment is always a challenge. This is why you must have a long range lens as 70-255 , 75-300 and more.
Keep in mind that stabilizer can help a lot since you are shooting photos in a dynamic and unexpected environment and your object may be on the move at any second.
Also, in many times, you cannot pick up the best position for light , so you must do your best and take many pictures as you can.
